Downloads for unsupported distributions:

All packages and repositories are digitally signed by the OpenPGP key with the following fingerprint:

B37D 9040 098C 3DEE E00F 6D08 A357 43EA 6773 D225

We recommend that you do not install any packages which are not signed by that key. If you use the correct "eid-archive" package for your distribution, the correct key will be automatically configured and you shouldn't need to worry.

Reading card fails?

The FAQ-section explains how to check this.
